The quality of lame preset=standard is extremely high.
You can certainly use ac3 if you like, it's just very
slightly less portable... Using dx50 and mp3 makes it
playable on more targets. BTW, as far as I know, the
dx50 switch only affects the header of the avi file,
and doesn't change the video encoding parameters at all
from the "lavc default". But it makes a huge difference
when it comes to playing the file on bran-dead windoze
based players.

The only thing I might suggest adding to your script
would be to add nr=50 to lavcopts, and to make use
of eq2 when you need to add some "punch" to the video...

For example:

 -vf eq2=0.9:1:0:1.05

Will punch up the video a bit for a small viewing device.
nr=50 is to make your file smaller, though you might want
to drop to nr=10 if the source is REALLY perfect. In either
case they will dramatically shrink the file size.

Remember to tell everyone how helpful the transcode list is
with mencoder questions ;^)
